Old, old B-side- Led Zeppelin song? Heartbreaker?

[le touch]

Hey guys-

A friend of mine bought a B-Boys single after seeing them open for Madonna in a galaxy far away in a time long, long ago. I don't remember the A-side, but I could swear the B-side was a B-Boys remake of "Heartbreaker" by Led Zeppelin. If not that- maybe another classic 70s rock tune (google turned up AC/DC's "Back in Black")?

I have not seen or heard of this single since then (1985?)- any clues would be REALLY helpful...

Thanks! Your ol' timey pal,

Thanks man...

So does the Zeppelin tune sound familiar too, or am I just mixing that up with a friend's hip-hoppy band who definitely did their own version of Heartbreaker? (The ol' grey matter just aint what it used to be...)

I would absolutely kill to hear "Rock Hard" to know for sure... any ideas how or where I might do this?

edit to add... I found the link to all the releases of it- still wish I could even listen to a snippet somewhere without having to purchase one of those.

They have used the better part of two Led Zeppelin songs on LTI.

You have this one.

And that one.
